Convert YAML to JSON
YAML is readable, but many APIs, validators and scripts need JSON. Paste a YAML snippet and this converter parses it into structured data, then prints formatted JSON with two-space indentation. It is a fast way to check config examples, move values into code or debug a YAML file by seeing the parsed structure.
Helpful for DevOps and documentation
YAML syntax can be sensitive to indentation. If a file fails to parse, the error message can point you toward the section that needs cleanup before conversion.
Frequently asked questions
Can it parse YAML arrays and objects?
Yes. Standard mappings, sequences, strings, numbers and booleans are converted to JSON.
Why did my YAML fail to parse?
Common causes include inconsistent indentation, missing colons or tabs where spaces are expected.
Does the YAML leave my browser?
No. The conversion runs locally after the page loads.
